Keeping your brand visible, strong, positive and focused will set you apart, maybe even be the key difference in being selected verses overlooked.
Step back from your business, walk back in (mentally or physically) and review what you see with new eyes, the eyes of your prospective buyers. Does it make a statement of clean, fresh, edgy, top-of-the-line or seem raveled at the edges, sad or even desperate? Can you identify the "core value" which the business operates from- what is your primary focus and goal; does the client know it without a lot of words and explanations?
How does your "brand" confirm or deny the message?
Hard questions, harder answers which are required to send the most impactive message possible!
Cutting through the clutter and showing value starts with the first impression- your signature of who you are as a business, i.e. your brand!
